Depending on the composition of the primary MC carbide and the constituent elements present in the alloy, sub-sequent solid-state transformation may decompose the MC carbide into a variety of M 23C 6,M 6C, and M 7C 3 carbides during heat treat- 2. Incubate at 35°C for 24 or 48 hours. If testing is performed after 24 hours it is recommended that a 2.0-mL portion be removed aseptically for the test. If negative, the remaining broth should be reincubated for an additional 24 hours and retested.

reagents with various ore-types, the practice of "custom-designing" a unique reagent or reagent formulation for individual ores has become increasingly common. Although there are a host of factors which have a bearing on any plant operation, we believe that the choice of chemical reagents is often under-appreciated. While many
